摘要： A voltage controlled oscillator of a phase lock loop responds to a phase error signal having a value commensurate with the phase difference between input and output signals of the loop, wherein the phase difference extends over more than a one cycle difference of the loop input and output signals. The phase error signal is derived by mixing the loop input and output signals to derive a pair of signals having amplitudes representing orthogonal components of the difference frequency of the loop input and output signals. In response to the signals representing the orthogonal components, signals are derived indicative of the whole number cycle difference of the input and output signals, fractional cycle difference of the input and output signals, and a combination of the amplitudes of the signals representing the whole number cycle difference and the fractional cycle difference of the input and output signals. The latter combination indicates the amplitude of the arc whose tangent is the ratio of the input and output signals even though the loop input and output frequencies differ.

摘要： An indication of the noise content of data bits on a signal line is derived by sampling the amplitude of a signal on the line several times during each of the data bits to derive for each data bit a several bit binary word. Each bit of the several bit word has a value dependent on the amplitude of the signal on the signal line at the time the sample is taken. In response to the number of binary value transitions in each several bit binary word an indication of the noise content of each data bit is derived.

摘要： An output of a local oscillator is synchronized to received bits of a digital bit stream by sampling the binary value of each of the received bits several times during each of the received bits, to derive for each received bit a several bit binary word representing the sampled values. A memory is addressed in response to the binary value of the several bit binary word to control the local oscillator synchronization. The synchronized local oscillator controls the sampling times of the plural samples of each of the received bits so that the binary value of the word controls the oscillator synchronization and the sampling times. The addressed word in the memory determines the value of the received bit, controls the oscillator synchronization, and provides indications of sync lock and unit content of each received data bit.
